Bioregion

Atlantic Forest

Also known as: Mata Atlântica, Bosque Atlántico, Selva Paranaense

A long narrow coastal biome that once covered ~1.3 million km² along Brazil's Atlantic coast — now reduced to ~12% of its original extent, but still one of the most species-dense biodiversity hotspots on Earth. Home to ~20,000 plant species (half of them endemic), the source of cultivated yerba mate and several pineapple lineages, and the bioregion in which most of Brazil's population now lives. The forest survives in a patchwork of remnants from Rio's *Tijuca* urban forest to the *araucaria* highlands of southern Brazil.

Why this entry

The Atlantic Forest is the bioregion where 70% of Brazilians actually live — the population centers of Rio de Janeiro, São Paulo, Curitiba, and Porto Alegre all sit within or adjacent to its remnants. Future listings of urban-adjacent aligned commerce in Brazil — agroflorestas, organic feiras, yerba mate cooperatives, Mata Atlântica reforestation projects — land here.

What’s distinctive

The forest is climatically and ecologically variable along its 3,500 km north-south span — from semi-deciduous tropical forest in the north, through coastal restinga and manguezais, montane Atlantic forest in the Serra do Mar and Serra da Mantiqueira, to the Araucaria angustifolia (Paraná pine) highlands of the south. Endemism is exceptionally high — the forest has been an “evolutionary island” separated from Amazonia by drier Caatinga and Cerrado biomes for at least several million years.

The biome is the wild source of Ilex paraguariensis (yerba mate), several Bromeliaceae (including ancestor lineages of cultivated pineapple), the heart-of-palm species Euterpe edulis (juçara), and Hevea brasiliensis (rubber tree, though the rubber economy centered on Amazonia). The Tupi-Guarani-speaking nations of the coast cultivated cassava, peanut, cotton, tobacco, and a diverse home-garden agroforestry whose patterns persist in contemporary smallholder farming.

Indigenous and contemporary

Tupinambá, Pataxó, Guarani-Mbyá, Guarani-Kaiowá, Krenak, Tupiniquim and many other Indigenous peoples whose ancestral territories overlap the modern coastal megacities continue to maintain forest-management knowledge and assert land rights. Brazilian agroflorestal (agroforestry) movements — Ernst Götsch’s syntropic agriculture most famously — are concentrated in the Atlantic Forest and offer reproducible models for restoring degraded land.
